‘TWO Weeks Notice,” the first romantic comedy teaming Sandra Bullock and Hugh Grant, evokes such deja vu, you’d swear you’d already fallen asleep on the damned thing in the middle of the night on HBO.

What seems like a dream team on paper is more of a tedious nightmare on celluloid, where Bullock and Grant are trapped with their well-worn screen personas in a dumb, ultra-predictable movie.

It may have added $24 million to the city’s economy – but this lead-footed romp reminds us roughly every 30 seconds that no matter how strenuously they bicker, these stars are no modern-day Tracy and Hepburn.

Bullock’s character, Lucy Kelson, is a lawyer and political activist cut from the standard Bullock mold – a loudmouthed tomboy, a bit of slob and a klutz.

Grant plays George Wade, an irresponsible, immature millionaire playboy – stifle those yawns – who serves as the public face of his brother’s real estate empire in New York.

He may be a figurehead, but George is somehow responsible for hiring the company’s chief counsel, a position he usually hands over to girlfriends with dubious credentials.

As if this weren’t hard enough to believe, George whimsically decides to fill the job with his sworn enemy, Lucy – whom he buys off by promising to spare a community center near her home in Coney Island from the wrecker’s ball.

Lucy loathes George, but she throws herself into the work – even negotiating a tough settlement with George’s ex-wife, though her background is in real estate law.

She finally gives her notice when George calls her cell phone during her best friend’s wedding – though the pal (Heather Burns) points out if Lucy hadn’t wanted to be disturbed, she wouldn’t have taken the call.

George sabotages Lucy’s attempts to find a new job – but suddenly relents when he discovers a replacement in June (Alicia Witt), who has no inhibitions about mixing business with pleasure, especially during a midnight game of strip chess that a jealous Lucy walks in on.

It would be nice to report that Grant and Bullock have great chemistry, but the truth is that they both indulge in their own brand of shameless mugging without much regard for each other – until the inevitable clinch.

It doesn’t help that Marc Lawrence (who makes an inauspicious directing debut after writing Bullock’s far more lively “Miss Congeniality”) has churned out clunky repartee that would challenge even Tracy and Hepburn.

Bullock: “I think you’re the most selfish human being on the planet!”

Grant: “Have you met everyone on the planet?”

Robert Klein and Dana Ivey are wasted as Lucy’s liberal parents in this profligate production, which lavishes millions on a waterfront circus (complete with a cameo by an orange-haired Donald Trump), a toilet stop in an RV stuck in a traffic jam on the Queensboro Bridge – and a romantic helicopter ride over Manhattan.

“It’s really amazing what dreams and lots of money can do,” gushes a converted Lucy – yeah, a romantic comedy as expensive and brain-dead as “Two Weeks Notice.”
